摘要

用去离子水对木薯叶粉进行简单洗涤，制备了低成本的吸附剂。测定了该吸附剂对亚甲基蓝(MB)的吸附性能。研究了溶液pH值在2 ~ 10范围内变化的影响。CLP对MB的吸附动力学符合准二级动力学模型，洗涤前后的k值分别为0.087907 g mg -1 min -1和0.094081 g mg -1 min -1。两种吸附剂的吸附等温线均符合Langmuir等温线模型，qm分别为178.5 mg g -1和243.9 mg g -1。通过在不同浓度的MB溶液中加入NaCl，考察了干扰离子的存在。

Preliminary Studies of Cassava Leaves’ Ability to Remove Dyes from Water

Low-cost adsorbents from cassava leaves (CLP) were prepared by simply washing the leaf powder with deionized water. The adsorption of methylene blue (MB) from the aqueous solution was measured in order to examine the adsorbent performance. The effect of the pH of the solution was studied by varying pH from 2 to 10. The kinetics of MB adsorption onto CLP followed the pseudo-second-order kinetic model with a k -value of 0.087907 g mg -1 min -1 and 0.094081 g mg -1 min -1 for CLP before and after washing, respectively. The adsorption isotherm for both adsorbents followed the Langmuir isotherm model with qm values of 178.5 mg g -1 and 243.9 mg g -1 . The existence of disturber ions was investigated by adding NaCl into the MB solutions at a variety of concentrations.
